What is a characteristic feature of the TH-73A's landing gear system?

• A. Fixed gear
• B. Retractable gear
• C. Skid design
• D. Tricycle arrangement

Answer: (C)

The TH-73A is designed with a tricycle arrangement for its landing gear system. This arrangement features a nose gear at the front and two main gears located towards the rear of the aircraft, which provides excellent stability during ground operations. The tricycle design allows for better visibility on the ground and aids in preventing the aircraft from nosing over, especially during landings and takeoffs.

In the context of the other options, the fixed gear and retractable gear designs do not apply to the TH-73A, as it is not designed with either type for performance or operational efficiency considerations. Additionally, a skid design is not characteristic of this aircraft, which is more suited to rotorcraft or some weight-sensitive applications. The tricycle landing gear is optimal for the TH-73A, providing a balance between operational utility and structural integrity.
